Que? = What?
Por que? = Why?
BTW I got a temp job about two years ago stuffing envelopes. It was only one day but it was hell. Standing in a an air conditioned but nonetheless still too warm warehouse, doing nothing but putting catalogs in envelopes and then sticking a mailing label on them. For 8 hours.
I'm not sure I could ever do another job that requires you to stand for so long. My last few regular jobs were all of the sitting variety. Which is still not awesome but much, much better than standing.
